What type of welding machine on eBay should i get?

A rod welding machine will be a good start. In addition, you can use most of the work done great arc welding to complete. When you need to enter a widely used tig or mig welding work, it's time to consider buying one. But this does not mean that you will throw away your old reliable welding machine. It is still your main welding tool. I have a 300 ampere of electric welding machine, bought almost as much ($300.00).
